Overview – DNA Twin TestingKnowing whether twins are identical or fraternal is difficult to base on appearance alone. DNA Twin testing aids in viewing with accuracy whether a set of twins are identical or fraternal. Identical twins are genetically identical and will share exactly the same DNA profile, whereas fraternal twins only share approximately 50% of their DNA in common. A DNA sample is collected in the privacy of your own home using buccal swabs (mouth swabs) and sent to our laboratory for testing. The typical turnaround time for testing is 3 to 5 business days. When testing is complete, you will receive a full laboratory report certifying the results of your DNA Twin Test.
How Does DNA Twin Testing Work?
The DNA twin testing kit contains four easy-to-use mouth swabs designed to painlessly collect a DNA sample from each individual for analysis. The mouth swab collected contains cells in which most of them contain a full set of genetic information in the form of DNA, short for deoxyribonucleic acid. An individual’s DNA acts as a “genetic blueprint”, and like a fingerprint, is unique between each person. Once the sample has reached the laboratory, the DNA is extracted from the cells and undergoes a process called PCR (polymerase chain reaction), which amplifies specific regions of the DNA. These amplified regions are carefully examined for a DNA pattern. The DNA patterns of the twins are then compared with each other. Based on the comparison performed, it can be conclusively viewed whether a set of twins are identical or fraternal.
